Midfielder Mitch Duncan was charged with striking the Swans' Tom Papley and the club will decide if they will take his case to the tribunal on Tuesday morning.

Duncan's indiscretion saw Papley awarded a free kick in front of goal at a critical time in the last quarter of the Cats' loss to Sydney at Simonds Stadium.

Hawthorn star Luke Hodge was also banned last week for striking Papley, who has drawn criticism for going to ground too easily.

Duncan risks a two-game ban if he chooses to fight the charge at the tribunal.

The duo's disciplinary issues couldn't have come at a worse time for the Cats, who will be without skipper Joel Selwood until at least the end of the home-and-away season.

Selwood underwent surgery on a syndesmosis ankle injury on Monday afternoon and is fighting to be fit to return for the finals.

"Everything went according to plan, which is really pleasing," Hocking said of Selwood's operation.

"From here it's all about progression now. People probably want timelines, but the expectation with the surgery is that he'll be back training in three weeks.

"From there he'll do everything in his powers to recover.

"He's shown throughout his career that he does recover really well.
